php - Symfony2: Preventing input in a money field is negative -

I want to prevent negative values ​​in a Symfony2 Formbuilder money field, but a minimum (0) or range (min) = 0) Adding emphasis on the annotation of the attribute in the unit does not work: The attributes in the unit are displayed as follows:

  / ** * @ORM \ column (name = "value ", @ Type =" integer ") * @Assert \ Type (type =" integer ", message =" value {{value}} is not a valid {{type}}. "* @asset \ range (min = 0) * @wor int * / no G $ value; / ** * @ORM \ Column (name = "setupFee", type = "integer") * @Assert \ Type (type = "integer", message = "value {{value}} is not valid { {Type}}. ") * @Assert \ Range (min = 0) * @var int * / private $ setupFee;   
 The formatting looks like this:  
 where ('dedicated circuit contract is NULL');}, ('product' description ' , 'Textera', Array ('label' = & gt; 'producents:', 'atric' => array ('style' = & gt; width: 350px ',' rows' => 4,) ) - gt; add ('value', 'money', array ('label' = 'gt;' nettoparis: ',' divisor '=> gt; 100)) - & gt; ('SetupFee', 'money', array ('label' = & gt; 'Einrichtungsgeb ¼hr:', 'divisor' => 100))
